Will do, thanks

Thanks, sent by message. Update - tried on an Intel i5 and same issue on export sadly

I'm on a Rizen 3 with AMD Vega8 and 14 GB ram, dx 12 and latest drivers. Have also tried the CPU option you mention. I've done plenty of similar edits before but never come across this. I was on the latest version of videopad but tried rolling back to no effect too. The odd things is, after 3 or 4 attempts the preview (right below) starts to show the distortion too. I've tried re-loading the source foortage (which is all from a single file with single aspect ratio and resolution) but when I do the original footage seems fine in the preview again, but still get the corruption (as left) on a number of transitions (but weirdly, not all of them) when I export (tried MP4, Mpeg, avi etc all with same result). Any thoughts very welcome. edit - I tried to paste screenshots in to this but they vanish on posting

Hi. I've been editing clips together which look fine in the preview, but when I export I get really blocky distortion on several of the inserted clips for several seconds before they revert to normal. I've tried different frame rates and resolutions, and different formats but with the same outcome. I'm currently on version 13.5 free. Any ideas? Thanks.
